Chain Keeper

The Chain Keeper is a guide to keep your chain right where it belongs. Mounted in place of a front derailleur, the Chain Keeper works with single chain ring drivetrains using a narrow chain. The chain block surrounds the chain as it meets the chain ring and prevents it from skipping off.

Did you know that Chico’s annual Bidwell Bump mo Did you know that Chico’s annual Bidwell Bump mountain bike race predates the first Repack?! 
  It’s a beautiful rugged loop with a creek crossing in Upper Park, and registration is still open for this year’s October 5th running. Head over to @bikereg and type in Bidwell Bump to get in on this historic race, and all proceeds go to Velo Trail Works. 
  Also, if you want to read a hilarious recounting of the first race in 1976 by local legend Chuck Bodfish (keep in mind, mountain bikes weren’t really invented yet), head over to the PAUL Comp website and type “Bidwell Bump” into the search bar.
